LOOIVL Specification of Letters Patent.

Patented May 24, 1910.

Application filed September 8, 1903. Serial No. 172,204.

To all whom it may concern:

Be it known that I, ROBERT H. H. HUNT, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements in Looms,of which the following is a specification.

My invention relates to improvements in looms, the object of myinvention being to provide an improved loom which will dispense with thenecessity of replenishing a shuttle with filling thread, therebyeconoinizing, first in avoiding the labor of making such replenishments,secondly, in the increased efficiency of the loom due to the saving oftime which is at present consumed in stopping to fill the bobbin withthe shuttle, thirdly in reducing the amount of yarn waste attendant uponthe usual method of weaving, fourthly in the saving of power, requiringless force to operate the loom, fifthly in the avoidance of breakagesboth in the warp and in the filling thread on account of the reducedstrain upon said threads, siXt-hly, in the first cost of the loom,permitting a lighter and simpler form of loom.

The main advantage attendant upon my improved construction is the savingof labor in the superintendence of the looms and in the supplying theshuttles with filled bobbins in the place of the empty ones. It isestimated that with this improved loom an operator can attend to manymore looms than with the old method of weaving, so that each loom whiledoing at least as much work as in the old styles costs a small fractionof its former cost in wages. A further advantage is that the cloth sowoven is of uniform quality and of great strength.

My invention resides in the improved construction and arrangement ofparts for obtaining the above results.

In the accompanying drawing, Figure 1 is a front elevation of theimproved loom; Fig. 2 is a side view of the same; Fig. 3 is a sectionalview of the auxiliary picker stick; Fig. 4c is a top plan view of theend of the lay and of the measuring device adjacent thereto; Fig. 5 isan end view of the same; Fig. 5 is a broken perspective view of the endof the measuring arm; Fig. 6 is a broken plan view of the front-of theloom;

In this method of weaving, instead of the filling thread being suppliedfrom a single source, namely, a bobbin carried in a shuttle, whichsource is replenished from time to time as exhausted, the filling threadis supplied from two separate sources, one at each side of the loom,each source of supply being sufiicient for an indefiinitely long run ofthe loom without replenishing. The filling threads are taken up fromsaid sources alternately, and are laid in the warp in the mannerillustrated diagrammatically in Fig. 23. The thread fed at each side ofthe loom is cut into lengths, each twice the width of the fabric, andeach such length is doubled upon itself in the middle with a pick fromthe opposite side between the two halves, the ends of the length beingcarried in succession to the opposite side of the loom, while the middleof the length is left at the edge of the fabric on the same side of theloom from which the thread was taken, such lengths being suppliedalternately from.

opposite sides of the loom, in the following manner :-The thread carriertakes the cut end of the thread and lays in the warp the first half a(Fig. 23) of the loop or length from the source of supply on one side ofthe loom; itthen takes the end of the thread from the other side thefirst half 6 of the loop or length from that side; while it is doingthis the measurmg device is measuring off the remaining half a of thefirst loop or length, so that when the thread carrier has returned, saidhalf is measured and cut off, and the thread carrier now takes up theother end of the first length and carries it across and lays it in thewarp and then in like manner takes up the second half 65 which has alsobeen measured and cut off and lays that in the warp. The process is thenrepeated. Before proceeding to the description of these several partsthe general construction of the loom may be particularly described, and,re ferring to the drawing, it will be seen that 1 represents the maindriving shaft having fast and loose pulleys at one end and connected atthe other end by toothed wheels with the counter shaft 2. Said shaft 2is connected by means of a train of gears 3 with a cam shaft 1 extendingacross the loom at the lower part thereof and having mounted thereoncams 5 for operating the various parts of the mechanism. The warp is fedin the usual manner, and the heddles 6 are operated by the harness 7,also in the usual manner.

8 represents the lay which extends beneath the shed of the warpv andover which passes the thread carrier 9.

The filling thread may be wound on large bobbins or spindles which areplaced in any convenient position for feeding to the loom. I have inFig. 1 shown the same as placed upon brackets 10 at the sides of theloom, but other modes of supplying the filling thread will be described.From each bobbin the thread passes through a guide loop 11 secured upona bracket 12, which is attached to the frame 13 of the loom, and thenpasses through a guide 14 mounted upon the swinging feed plate 15 whichresents the thread to the thread carrier. S aid guide is formed with anirregular slit 16 on one side by which to insert the thread into theguide without threading it through the end. The irregularities of theslit prevent the thread from accidentally jumping sidewise out of thegiude. From the narrow end of'said guide, the thread is continued downbetween the swinging feed plate 15 and a spring tension plate 17 whichis secured to said feed plate 15 to move therewith and extends over saidplate, normally in contact therewith. Said feed and tension plates areeach bifurcated, as shown, and inof the loom and lays the space .betweenthe two fork members of the plates are located the shears 19 which severthe thread. Said thread, shown at 20, passes over pins 21 which aresecured to the tension plate 17 and project into holes 22 in the feedplate 15, said pins thus forming guides for the thread to present thesame in proper relation to the jaws or nippers of the thread carrier.The inner blade 23 of the shears is fixed, while the outer blade 24 ispivotally mounted, as shown at 25, and the back of said movable blade 24engages a bridge 26 connecting the two fork members of the tension plate17 and presses said plate outward when said shears open, thus separatingsaid tension and feed plates and allowing the thread to pass freelytherebetween. Upon each blade of the shears is secured a gripper 27 inthe form of an elongated loop of spring wire, the inner side of whichenters a groove 28 formed in the edge of the opposite blade, and gripsthe thread against said edge. The spring loops grip the thread justbefore it is severed and retain the ends of the thread in position to besuccessively presented to the jaws of the filling carrier.

To actuate the movable blade there is provided a cam plate 30 fixedlysecured upon the frame of the machine, and there is a roller 31 on theend of an arm 32 extending inward from said movable blade substantiallyat right angles thereto. As the feed plate rocks upward, said roller 31travels on the outer side, (that is, the side farthest from the pivot ofthe feed plate) of a cam switch 33 pivoted as shown at 34, in a camgroove in said plate, the lower end of said cam switch being normallypressed inward or toward the plvot of the feed plate bya spring 36secured to the pivot pin 34: of said switch and bearing against a pin 36on said switch. As the feed plate swings upward, carrying with it theroller 31, the pressure of the tension plate 17 and bridge 26 againstthe back of the movable blade 24 holds the roller 31 against saidswitch. lVhen the roller arrives at the top of the outer path of the camgroove it passes between the upper end of said switch and the outer orupper wall of the groove, depressing the upper end of said switch andpassing over or around the same. Up to this point the shears have beenheld open. But when the roller passes around the upper end of the switchinto the inner path of the cam groove, and commences its downward orreturn movement, the blades are moved together, the thread is gripped bythe wire loops, and is severed between said loops. The cut ends of thethread are gripped, while the roller is passing down the inner or lowerpath of the cam groove. When the roller arrives at the end of said lowerpath and passes the lower end of said switch, it presses the lower endof the switch 33 upward, and passes under the same into its upper path,the lower end of the switch then swinging downward into its originalposition. Thus when the feed plate is swinging upward the shears areopen, they close when the feed plate begins to rock downward, theyremain closed while the feed plate is moving downward and then openagain when the feed plate moves upward as previously stated. Said feedplate is mounted upon a shaft 38 extending through an arm 39 attached tothe frame of the machine, the other end of said shaft carrying slidablymounted thereon a collar 137 pressed inward by a spring 138, and havinga pin 140 which enters a hole 141 in the end of a block 151 secured tosaid shaft 38, so that the collar 137 normally turns with the shaft 38,but by pulling the collar away from said shoulder it may turn freely onthe shaft. Said collar has secured thereto a crank 40 attached to apitman 41 carrying at its lower end a roller 42 working in a groove 43of a cam secured upon the shaft 4. The shape of this cam groovedetermines the directions and rates of movement of the feeder and theintervals of rest thereof which enable said feeder (and also themeasuring device, which is operated from the feeder, as will bepresently explained) to operate in harmony with the thread carrier. Uponthe same shaft 38 of the feed plate is secured a seg ment gear 44, whichmeshes with a gear wheel 45 loosely mounted upon a shaft 49 secured inthe frame of the machine, said gear wheel 45 having secured thereto to1'0- tate therewith a measuring arm 46, which extends first outward orperpendicular to the plane of the gear wheel (see Fig. 4) and then isbent again at right angles to itself or parallel with a radius of thegear wheel (Fig. 5) to a point over a curved measuring tube 47 slottedat its convex side, as shown at 47 which receives the thread measured bythe measurer 46. The arm 46 after passing beyond said measuring tube isbent inward at right angles to itself, and is formed with a V-shapedfront edge 48 (Fig. 5 to engage the thread and center it opposite to theslot in the tube. The upper end of said measuring tube is formed withthe edges of the slot flaring so as to insure the entrance of the threadinto said slot. The measuring arm 46 is adjustably secured upon the gearwheel 45 by means of a screw 49 and a slot 50 in said measuring arm.

51 represents a guide arm which extends upward from the end of themeasuring tube and insures the thread being guided into the upper endthereof.

To follow now the movements of the measuring and severing devices duringthis process, commencing at the time when the thread carrier is about totake the first thread and lay the first half of the first length in thewarp, it will be seen that the thread is held between the shears and theupper fork member of the feeder, the end being gripped by the springwire loop entering the groove in the upper jaw of the shear. The threadextends to this point from the bobbin through the guide 14. The lay 8 issubstantially at its most for ward position, and the nipper jaws of thethread carrier, (hereinafter described) are about to take the thread.When said nipner jaws take the thread the feeder has arrived at itslowest position, so that the roller 31 has reached the lower end of theinner path of the cam groove. The cam switch has then sprung inward, sothat the roller in returning is compelled to take the outer path and toopen the shear blades. This also separates the tension plate 17 from thefeed plate 15 and allows the thread to pass freely between them, andbetween the wire loops 27, as it is carried by the thread carrier to theother side of the loom. After this thread has been beaten into the clothby the forward movement of the lay, and the thread carrier is returningto lay a thread in from the opposite side, the feeder moves upward, andwhen the feeder is moving upward the measurer 46 is moving downward. Assoon as the feeder has reached its uppermost position, the roller 31moves into the inner path of the cam groove, and the shear blades movetogether so that the grippers 27 close into the grooved edges 28 of theblades, gripping the thread which is immediately cut by the shears, thegrippers retaining the cut ends. The measurer now returns, as shown inFig. 4, leaving a sufiicient length of thread measured off to be nextlaid in the warp. The feeder, ho ever, on moving downward stops short ofits first position at a point at which the nipper jaws of the threadcarrier will take the thread on the far side of the shears. When thethread carrier is thrown the second time to the other side of the loomcarrying the last end of the length of thread, the feeder moves on theshort distance necessary to bring it into the position first referredto. The operation is then repeated as before. It is to be understoodthat a similar operation is taking place at the opposite side of theloom, the parts being precisely the same in every respect, the onlydifference being in the time of the operations on the two sides of theloom, the operations following each other at opposite sides, theoperation at the left side being one pick in advance of those at theright side.

My improved thread carrier 9 has a main body portion. in proportion toits 60 which is of small thickness widtlrand to said body portion aresecured at each end spring fingers 61 which extend substantiallyparallel with each other, but converge at the ends, as shown, andterminate in points. One of said fingers has a thin rib 62 projectingfrom its inner surface, said rib entering a groove or slot 63 formed inthe other finger, and there is also a pin 64 which by its engagementwith said groove serves to center said rib therein. Said fingers springtogether so that their ends form nipper jaws to grip the end of thethread very securely. The jaw next the reed is slightly longer than theother. For the purpose of opening said jaws to grip the thread there isformed on the front finger the inwardly extending cam or boss 65 andwhen the thread carrier has arrived at the proper place for the jaws toopen, a spreader rod 66 having a wedge shaped end enters verticallybetween the two fingers, in front of said cam or boss, said fingersbeing sufficiently far apart to permit said wedge shaped end to enter.lVhen the thread car rier moves forward to take the thread, the camshaped part 65 of the front finger and the rear finger passing on eachside of the spreader cause said fingers to spread and the jaws to open,in position to take the thread. Below the cam shaped inward projection65 there is a smaller cam shaped inward extension 67 also from the frontfinger. This is for the purpose of spreading the fingers to drop thethread, and this smaller exten sion is actuated by a second spreader 68which does not rise so high as the first spreader and thus does not risehigh enough to engage the wider cam or extension 65. It rises onlysufiiciently high to engage the lower and smaller extension, but yet itspreads the fingers sufliciently far to allow the end of the thread tobe drawn out and around the hook. For the purpose of actuating saidspreaders I provide the following construction. 69 represents a platesecured to the frame, suitably braced and extending inwardly underneaththe lay. Said plate has formed therein a cam slot 70 which extendsdownwardly and forwardly, as shown, and in said slot moves a pin 72 onthe end of a lever 73, said lever being fulcrumed 011 a bracket 7 4depending from the under side of the lay, the pin, and the end of thelever carrying the same, being suitably supported against forward andbackward movement by means of two vertical guide bars 73 depending fromthe lay, between which the end of the lever has a vertical movement. Itwill readily be seen that, on account of the forward and downwarddirection of the slot, when the lay comes forward, the end of the lever73 drops, and rises again when the lay moves backward. To the oppositeend of the lever 73 is secured the spreader 66. The other spreader 68,which has a smaller vertical movement, is secured upon the end of anauxiliary lever 75 fulcrumed at 77 on a bracket 76 depending from thelay, and pivoted as shown at 77 to the lever 73. Thus the forwardmovement of the lay raises both of said spreaders, but the outerspreader 66 more than the inner spreader 68.

In the main body of the thread carrier is formed a longitudinal slot oropening 78, in the center of which is a transverse pin 79. The pickerstick 80 does not engage the thread carrier directly but is connected bya link 81 with a picker 82 which slides in a groove or channel 83 in thelay and has an upwardly extending hook 84 which brings to rest thethread carrier, by engaging the end of the body 60 thereof. Upon saidpicker is pivoted an upwardly extending latch 85 which is pressed upwardby a spring 86. When the thread carrier arrives at said picker, the pin79 passes over said latch, the latch then immediately springing upwardbehind the pin and preventing rebound thereof. The picker stick thenmoves slightly forward with the thread carrier. It is arrested howeverby means of the same arm 87, secured upon the rock shaft 88, whichserves to vibrate the picker stick, said arm 87 being now made ofconsiderable length so that its end arrests the picker stick at theproper time. hen said picker 82 returns and arrives at a point in itsmove ment at which it is to impart momentum to the thread carrier, theupper surface of said latch 85 is engaged by the overhanging top of thechannel 83 so that the latch is forced thereinto, and the thread carriercan pass freely over the same and escape from the picker and be shotforward therefrom. Said picker stick is pivotally mounted at its lowerend upon a bar 89 secured upon the frame of the machine and has an arm90 extending at rightangles thereto which is connected by a strap 91with a horizontally extending arm 87 upon a rock shaft 88 mounted at theside of the loom, said rock shaft being operated by means of an arm 96Lextending inwardly therefrom and having a conical hard rubber roller 95engaged by a cam 96 on the cam shaft 1. Said cam is very abrupt in itsforward or advancing portion, so that the rock shaft is given a suddenrocking movement which transmits a sudden inward movement to the upperend of the stick and throws the thread carrier with great velocity fromone side of the loom to the other. An important advantage of the aboveconstruction is that the picker sticks are now within the frame of theloom instead of at the outside thereof. Thus the floor space occupied bythe loom is greatly reduced laterally, leaving more room to pass betweenthe loom, and permitting of more looms in a factory of given dimensions.When the lay moves forward the picker stick moves forward with it andpasses out of engagement with the end of the arm 87 and thus is enabledto advance laterally, which it does under the action of a spring 97connecting it with the lower end of the other picker stick, which isitself operated by means of the strap 91 and the rock shaft 88. Thus thepicker stick and the picker move forward. As the thread carrier arrivesat the opposite side of the loom and enters the housin 98,-its motion isretarded, first, by means of a spring plate 99 secured to said housing,and then by means of a lateral boss or extension 100 on the threadcarrier which engages a bent wire 101 pressed inwardly by a spring 102and mounted upon the upper end of a vertical rock shaft 103 in the lay,said rock shaft being bent forward at its lower end as shown at 104 andthere connected by a wire 105 with a rock shaft 106 at the other end ofthe loom, similar to the shaft 103 except that the lower end now extendsrearwardly as shown at- 107 so that said rock shafts move in unison. Theobject of this is, as will be presently explained, to effect anautomatic stoppage of the machine in case the thread carrier does notarrive at said wire 101, by the time the lay has advanced to apredetermined point. Upon the under side of said housing is formed a rib109 which bears upon the nose of the thread carrier and holds it down toprevent it being lifted by the spreader as the spreader moves up to bein position to open the jaws. iVhen the thread carrier has arrived atthis position the rear nipper jaws of the thread carrier have drawn thethread nearly up to the selvage, and it is necessary to lead the threadinto the selvage slowly. It is therefore necessary to move the threadcarrier forward slowly at this point. For this purpose there areprovided, on the front portion of the frame of the machine, bell cranklevers 110. One arm 111 of each lever is engaged successively by forwardextensions 112, 113 from the lay. The extension 112 engages said arm 111near the extremity thereof, so as to impart a comparatively slow motionto said arm. The other arm of said lever is thus moved behind the pickerstick and pushes it forward, slowly at first, to let go of the thread,when the bell crank lever is engaged by the extension 112, but when thelay has come sufficiently forward for the other extension 113 to engagesaid arm, then, on account of the point of engagement being much nearerthe fulcrum, the forward movement of the lay imparts a much more rapidmovement to said arm and to the picker. This rapid movement is for thepurpose of moving the thread carried forward quickly, to take a newthread after the end of the thread has been laid in.

Should the thread carrier not reach home in due time by reason of a warpthread breaking in front of the reed, or from other cause, the loom isautomatically stopped in the following manner. It has been stated thatwhen the thread carrier arrives at its housing it engages a bent wire101 actuated by a spring and thus rocks a vertical rock shaft 103. Aforwardly projecting arm 104 formed on the lower end of the rock shaft103 is thus caused to move inwardly, that is, from the side of the loomtoward the middle thereof. It thus escapes engagement with a finger 114formed upon a plate 115. But if the thread carrier should not havereached home as aforesaid when the lay is moved forward, then said end104 would not escape said finger 114 but would engage it, and, by reasonof the end of said arm 104 being inclined or cam-shaped, it would liftsaid finger and thereby lift said plate 115 into the path of a tongue116 carried forward with the lay. The effect of throwing up the plate115 in the path of the tongue 116 is to move said plate 115 forward.Said plate is pivoted on a slide 117 which is attached by means of a bar118 to the brake 119 so that when the plate moves forward it brings thebrake 119 up against the wheel 120. At the same time a finger 121secured upon an extension of said plate pushes the shipper handle 122out of a notch 123 in the frame, whereupon the shipper immediatelysprings inward, throwing the belt from the fast to the loose pulley. Itwill be observed that this takes place at whichever side of the loom thethread carrier fails to get home in time. For the two vertical rockshafts are connected by the wire 105 running across the loom, so thatthe rocking of the farther shaft also rocks the nearer, and, on theother band, should the thread carrier fail to get home in time at thefar end, then both vertical rock shafts remain stationary, and thestopping mechanism is set in motion.

I also provide an automatic stopping mechanism behind the harness. Thiscom prises a bar or frame 124 extending the width of the loom behind theharness and having secured thereon at short intervals wire arches 125extending upward between the threads of the warp and so shaped as toform a guide for an auxiliary flier 126 having flanges 127 which passunderneath corresponding shaped portions of the arches and also has afriction piece 128 which when passing into the housing 129 at each endis arrested by means of a spring 130 pressing upon said piece through ahole 131 in the top of the housing and preventing the rebound. Thisflier is actuated by means of an auxiliary picker 132 having a rear arm133 lifted by a stirrup 134 from an arm 135 on the same rock shaft 88 asthe main picker is operated by. When the flier 126 arrives at itshousing 129 it presses outward the bent arm 136 of a vertical rock shaft142, said arm being normally pressed inward by a spring 143. Said rockshaft has a lower arm 144 loosely connected with a lever 145, pivoted at146 upon the under side of the lay frame, said lever 145 having 111 likemanner, as the lever 104 a downwardly and forwardly sloping end 147which, when the lay is moved forward, lifts a finger 148 extending fromthe plate 115. Now if the flier has not been obstructed in its passageacross the loom, but arrives at its housing in proper time, thedownwardly and forwardly sloping end of the lever 145 is swung out frombelow the finger 148, so that when the lay moves forward it does notengage or lift the same. But if a thread breaks and falls across thepath of the flier in its passage in one direction, the thread is movedsidewise across the warp threads, and thus lying across the warp threadsprevents the free opening of the warp threads at this place in the nextshed. This in turn prevents the flier reaching home in time on its nextsubsequent pick. Then the end 147 does raise the plate 115, and thus theloom is stopped in like manner as was done by the arm 104. At the otherside of the loom the flier rocks a shaft 149 similar to the shaft 142except that the lower arm of said shaft extends rearwardly instead offorwardly, and is connected by a cord 150 with the arm 144. Thus, atwhichever side of the loom the flier fails to reach home in time, theloom is stopped.
